I posed between the respective key-bars 17 and The shaft 3, however, is normally prevented from rotation by means of a stopping mechism consisting of a stopping-disk 15, said disk being arranged in the space between the partitions 6 and 7 of the casing 1 and rigidly secured to the shaft 3 for rotation therewith The stopping-disk 15 is arranged horizontally between the partitions 6 and 7, and projecting from the under side of said disk are a plurality of projections or pins 16. The various pins 16 Y are so arranged as to travel in concentricallypgojections or pins 16, each key-bar bein a v a spaced aths of movement, so that a part extended lnto the path of movement of one of 'the projections 16 would not interfere or engage with any of the other pins or projections. ig.- 3 illustrates one arrangement of the pro j cations-16, and Fig. 5 a second arrangement of saidprojections, these figures illustrating that various arrangements may be-sutilized in the ractical embodiment of the invention. T e. o eration of the stop 'ng-disk 15 is governe by a number of key-bars, (indicated at 17 and 17 the key-bars 17 being. ar-v ranged upon one side of a line vertically central of the machine, whereas the key-bars 17 are arranged upon the opposite sideof such a line. The key-bars aforesaid are provided in a number corresponding. with the number of:

, operator will depress the key-bar having the ,10 numeral 32 upon its finger-piece. When 1 this key-bar is forced downwardly, the hook 21 thereof rides against the upper portion of '--the detent-ber 22, which detent-bsr has been men agement with the key-bar 17 (desigr 5 Irate at the numeral 50.) As soon as the hook'21 of-the key-bar (designated by the numere l 32) forces the detent-bsr 22 back as it en rges the same seid detent-ber is simultsneously disengaged from-the hook 21 of the zo .lrey-bar, (designated by the numeral 50,) perthe "last mentioned key-bar to move "upwa-rdly at its outer end, so that the pro- ]leotion :19 of this key-bar is disengaged irrom 'the pin or projection 16,- by which the.

25. Stppp'ing-disk has previously been held y from movement. The stoppingdisk, assoon csithe projection 19 above mentioned is disv engaged therefrom, immediately begins to turn under the actuation of the motor-spring 3r; 4 but the keybar having the designation 32 has now been engaged with the detent-ber, and the projection 19 which extends from this ,lrey-bar is in the pathilof movement of I one bf the projections lfi upon the stopping- 5 dish 15. As soon as the projection 16 of the I stopping disk 15 strikes the projection 19 of the'key-ber. (indicated by the numeral 32,) said stopping-disk is stopped trom rotation, and the positions of the spaces A of the strips 11 and 12 being arrcngedperticule rly with reference to the key-bars, the spices A having the sslery-marks 32 at its he'edwill ap-- pear before the sight-o enings Vertical guide-rods 28 at the rig t of, each sight-open- 5 ing 14 carry slide-frames 29, each frame being of a size sufiicient to inolose one of the day designations upon the plates 27 and one of the sale ry designstions'in the length of the columns of the spaces A, and the operator as soon as the machine stops upon depression of the key-bar designated 32 may readily grasp one of the slide-frames 29 until the'ssme is moved to the numeral in the length of the plate 27 at the left in Fig. 1,-and he will 5 5 immediately see that for ninety-five days work at wages amounting to thirty-two dollars a month the person is entitled to one hundredan d sixteen dollars and ninety-two cents. I i

It will be obvious that various other designations my be used as far as indicated metter carried by the plates 27 and strips 11 and 12is concerned, soas to adapt the machine embodying the invention'to uses in various businesses. However, such uses will not be described, as the mechanism may be employed in so many diii'erc'nt ways to accomtlic principle oi opplish the results so t s eretion. of the :machiu iuvoifi'eu. p

The belt or strip 11 rr atch in one direction, Whereas the belt or strip 12 rotates in the opposite direction, due to the arrangement of the gear-wheel S, and the gonr-wheels 9 and 10 preferably make two revolutions to one revolution of the Wheel 53, and in the construction illustrated such two revolutions will turn the belts or strips 11 and 12 just once with reference to the sight-openings 1%. It will be understood that the number oi the rollers 9 and l0" may be'incressed or decreased within the contemplation of the invention and as required by various modifications thereof. The projections 19 of the keybars 17 are conceved, preferably, upon one side, so as to permit engagement of t" e pins as the disk 15 rotates, the projections 19 being concsved on the opposite sides.

The advsnttges oi 'the invenivion from a practical standpoint are obvious, as itviill be seen that the operator of the machine can readily determine or secure the necessary calculation desired by him very quickly,

thereby increasing the amount of work which he may perform in an ascertained time to an extent which is of great importance for obvious reasons.

Having thus described the invention, what is claimed as new is 1. In a computing and calculating machine, the combination of a movable computing device, a rotatable stopping-disk operetively connected therewith, projections extended from the stopping-disk at dill'orent distances from the line of tllil s thereof, it plura-lity of key-bars, and members projected from the key-bers to onset with a single pro jection on the stopping-disk at a predetermined point in the movement of said disk.

2. A device of the character described comprising a casing, a computing device within. the casing and comprising sets of rollers and belts containing suitable indicin and mounted around said rollers, a revoluble disk connested with said rollers to move therewith and provided with a series of projections difierent distances from the center of rotation of said dish, a series of hey-bars arranged parallel in said casing and each of which is designed for contact with one o1": the projoctions on said disk, and a detentber mounted for engagement with said key-hers, as and for the purpose set forth.

3. A device of the character described com prising a casing, rollers mounted in said casing and containing piercing projections, and belts containin suitable indicia and travel ing around sai rollers in engagement with said projections, a revoluble disk connected disk, a series'of key-bars arranged parallel in said casingandeach of which is designed for contact with one of the projections ()Yl sftld disk, and a detent-bar mounted for gigsment with said key-bars, as and fort e purprising a casing, a computing device within.

4. Adevicc of the character described comsaid casing, a revoluble disk operatively connected with said computing device to move therewith, means for moving said disk and computing device, and provided with a series of projections, a series of key-bars mounted in said casing and extending through the front side of the same and arranged parallel, each oneof said key-bars being provided with a downwardly-extending hook, and a detentbar 22 pivotally mounted along the front side of the casing and spring-pressed toward the hooks of said key-bars, as and for the purpose set forth. 1

5. A device of the character described comthe casing and comprising sets of rollers and belts containing suitable, indicia and mounted around said rollers, a'revoluble disk coiinected with' said rollers to move therewith and provided with a series of projectionsat different distances from the center of rotation of said disk, a series of key-bars arranged parallel in said casing and each of which is designed for contact with one of the projections-in said disk, a detent-bar mounted for engagement with said key-bars, a vertical guide-rod secured on said or sing, and a slideframe designed to be brought infront of the indicia or other characters carried by said belts. v
